UNITED STATES PATENT A-IfEEICE RANKIN L. SHOEMAKER, OF NEW COMERSTOVN, AND FREEMAN R. WILLSON, JR., OF COLUMBUS, OHIO, ASSIGNORS TO THE JEFFREY MANUFACTURING COMPANY, OF COLUMBUS, OHIO.

PORTABLE ELEVATING-MACHINE.

SPECIFICATION forming' part of Letters Patent N0. 681,378, dated August 27, 1901.

T @ZZ whom t may concern.-

Be it known that we, RANKIN L. SHOE- MAKER, of New Comerstown, in the county of Tuscarawas, and FREEMAN R. WILLsoN, Jr. residing at Columbus, in the county of Franklin, State of Ohio,citizens of the United States, havel invented certain new and useful Improvements in Portable Elevating-Machines,

of which the following is a speciication, rei'- Fig. 4 is a section on the line y y of Fig. 2,

showing the framework and some of the parts attached thereto, looking downward. Fig. 5 is a side elevation looking from the left in Fig. 6. Fig. 6 is a side View of a modified mechanism embodying our improvements. Fig. 7 is an enlarged sectional side elevation. Fig. Sis an enlarged sectional rear elevation; and Fig. 9 is a transverse section of the lower portion of the supporting-framework and the machinery carried thereby as illustrated in Fig. 6. Figs. 10 and 11 are enlarged details of the mechanism for throwing the hoistingdrums out of gear. Figs. 12 and 13 are enlarged details of the elevator construction.

The operative parts of the mechanism are supported upon a car having wheels A A, adapted to fit ordinary railway-tracks, a bottom truck-body B, resting upon the wheelaxles, and an upper horizontally-adjustable table or bed C. The bed C carries corner-uprights D D and intermediate uprights D. The uprights are connected together by suitable sills or cross-girths E at suitable distances from the bed, and at the upper end of the main frame there are elongated laterally-projecting overhan ging frame-bars F F, the outer ends of which are braced by inclined beams or bars G. In the opposite direction there extends laterally from the main frame a supplemental frame having the top bars H and inclined brace-bars I for the supporting of 5o parts to be described. Upon the framework thus described are supported the mechanism for engaging with and elevating the material, the mechanism for screening and separating, the means for guiding the separated materials to their places of delivery, the parts by which adjustments can be effected of those mechanisms which can be moved upon the frame, the engine or motor, and the means for transmitting power from the latter to the various parts of the machine.

1 is an engine mounted ont-he bed C-and having its shaft connected by a chain l to the chain-wheel lb on the shaft 2. This shaft transmits power to the shaft 3 through the 65 chain 2a and the sprocket-wheell 2b. The shaft 3 has two loose bevels 5 5, which can be engaged with the shaft by clutches 4 4,

, respectively.

5ad is a bevel-wheel adapted to be engaged alternately with the bevels 55 or be disengaged from both.

6 is a shaft to which the bevel-wheel 5 is secured, this shaft extending downward at n the central vertical line of the bed and the car-truck. At its lower end it is provided with a bevel-wheel 7, which engages with la bevel-wheel 8 on a shaft 9, supported on the under side of the truck-frame. The shaft 9 is connected by a chain l0 to one of the car; axles. When one of the clutches 4 connects its wheel 5 to shaft 3, the latter, being in constant rotation, rotates the bevel-Wheel 5f, the vertical shaft 6, the bevel-gearing 7 8, and the car-axle, causing the car, with all of the partsv supported thereon, to move bodily along the track. It can be moved in the opposite direction by reversing the clutches at 4 4.

After the car has been brought to the desired place for working the clutches are put in their neutral position and the car is held stationary.

In order to adjust the upper bed and the operative parts supported thereon in horizontal planes relative to the truck, the'following devices are used: I

On shaft 2 there is a sprocket-Wheel 1l, which drives chain 11, the latter engaging with the sprocket-wheel 11b on a shaft 12, mounted j-ustabove the bed C. This shaft has two loose bevel-pinions 14, adapted' to be connected to the shaft by clutches 14, both wheels meshing with the horizontal bevelwheel 16 on a vertical shaft 15. The lower end of this shaft carries a spur-pinion 17,.. which meshes with a` circular rack 18, the latter being secured rigidly to the car-truck. If the clutches at 1-1a 14a are movedin one direction, the corresponding bevel-wheel 14 causes the parts at 16, 15, 17, and 1S toimpart rotation to the bed C and the parts above it, and by throwing the clutches in the opposite direction the other bevel-wheel causes the rotation of the bed in the other way.

After the car-truck and bed have been put in proper places, as above described, the operati ng mechanisms-are actu-atedI as follows:

2Dis afsprocket-wheelonshaft 2,connectledi witlil sprocket-wheel 21 on! shaft 22' by' thel chain 202,

23=is aspu'r-pinionon shaft 22, which` enL gages-with tfhe w-h'eel 24', there being at 23 a' clutch'c for connecting and disconnectingtheshaft 22 an-dl the spur-pinion 231. rllhe wheely is on the sha-ft 25, to whicliare secured'two rope-drums 26;

27 i'sa'arope running from each dfrum-l up along the inclinedbars1Gpassing overa-fixed" sheave 30;` thence downward t'o=` a movable sli'eawel 3D, thence` back# tor the1 fixed sheave; andifrointhere again to the movable one'. 'llhe shea-ve 30a isconnected by a= lin-k tioV the elevator-frame, and as this fram eissuspenedi ronrtfheshaft 29`at the top` the ropes, drums,

andi drnmsrotatilng devices can be used to'n by' the-weight of theconveyer-frame.

Power ista'ken from the shaft-2by chain 311` loaniintermediateshaft 321 This shaft is connected by a bevel-gear at 33 tothe shaft drum and screen being set at a relatively sharp inclination, so that the materials in them respectively will be advanced toward the lowerend and discharged.

The mechanism shown is principally used for elevating sand and gravel and then separating them, andi in such case the gravalwill ibe retained in ltheV inner screen and finally :delivered at its lower end, while the sand that is separated therefrom and is caught in the outer drum will be separately delivered. The gravel-receptacle is shown at 40 and the sand-receptacle at 41. With the receptacle T4'Ocommunicates the extensible and horizontally-adjustable delivery-chute 42, and with lthe receptacle 41y communicates and to it is adjustably secured the chute 43, these chutes ybeing adapted to deliver the materials which 'they carry downward tofcars, as at 4'4.. Y

Descriptionhas' been given aboveof the manner of'swinging outward the lbwer' end of the-elevator-frame aroundthet shaft 29 as an axis. When'the elevator-frame is being allowed to return toward the main frame', we' control its; downward movement as follows 45 is` afriction-drum onL theA shaft 25; is a liexible brake-band surrounding this' brake-drum`and having its ends connected to a lever 47, the crank-arm 4S of which` is connected to1 a link 49, These parts can be operated in any suitable way.n In onemechpivoted to-a lever 50, with which a; chain 51 is' connected, which runs over guide-pulleys 52andf dbwntoa handler-lever 53, accessible to the" operator. Inl the other mechanism illustrated the link is connected to bel'llever54', which inturn is connected to'levei 56 by a link 57.

What we claim isy 1^. InA an elevating and screening mechanism of the-character described, the combinationv of the wheeled truck-frame, the" main' framehorizon-tally adjustable on' tlietru'ck- `frame, the outwa-rdfswinging elevatorv suspenfded* at its upper' end from the main f'rame, thescreening' mechanism, the power' Vdevices on the-main frame, power-transmitlting devices connecting the power devices with the elevator-chains and with the'screenl ing devices, means fordetachably connecting `:the power devices to' the elevator-adjusting devices, reversible power transmitting. de'- ivices for detachably connecting the4 power vdevices toY the truck-wheels, and reversible ,Ipower-tra-nsmitting devices for detachably connecting the power devices tothe-means lby which the main frameis adj ustedE axially, y substantially as set forth. u Y
